Day 1:
We weighed all of our materials on the first day, and put our nail on the copper (II) chloride. The nail turned red and it was pretty cool.

Day 2:
After letting the nail soak overnight, we found that the solution turned green and a bunch of poop-looking copper was a product from the reaction. We then had to get rid of the nail and all the liquid by siphoning and pour water into the jar with the copper and siphoned off the water as well. The copper is left in the jar for the weekend and now we wait.

I thought this lab was really repetitive, we would clean our product and then measure the mass. I didn't understand the purpose of this lab because it didn't teach me anything. However your description of "swamp water" is spot on.
ReplyDeleteYour pictures turned out really well and I like them a lot. I felt this lab helped me with applying a percent yield problem to real life to find if iron acted as a plus 2 or plus 3. I also thought it was cool how much the nail changed.
ReplyDeleteYour pictures are great! I also liked how we got to practice percent yield in real life because I had kind of been struggling with that. It was really neat to see the way the nail changed after reacting with the Cu (II) Chloride.
ReplyDeleteI agree with Abby, it didn't teach me anything really either. I think it was supposed to reinforce the percent yield because of the problem twixt the two Iron cations, but it was really pretty easy, reviewing what we had already done.
ReplyDeleteGoing along with Tom and Abby, this lab was nothing new to us. THANK GOD. I was grateful for feeling comfortable during every aspect (i.e. prelab, procedure, calculations). Pictures depict lab very well!

ReplyDeleteAs I said on Lindsi's blog you have a nice summary of the lab! I do agree this lab was repetitive, but the work up at the end was great test review!
ReplyDeleteI felt this Lab more or leass was just rinsing out a baby food jar over and over again. Though, I am glad that it wasn't too hard of a Lab, I actually thought it was pretty cool, also the calculations actually served as extra practice and helped me come time for the test. Also those pictures came out great!
